Multi-capability platform for testing materials in high temperature and pressure hydrogen pre- and post-combustion environments

A method for testing mechanical and environmental properties of a metallic specimen under hydrogen exposure, the method comprising:

• electrolyzing water to generate hydrogen via a proton exchange membrane (PEM) cell;
• introducing hydrogen generated by the PEM cell into a test enclosure containing the metallic specimen therein;
• regulating pressure and temperature within the test enclosure, the pressure ranging from atmospheric pressure to at least 6000 psi, the temperature ranging from room temperature to at least 1200° C.;
• and
• measuring a mechanical response or an environmental response of the metallic specimen to assess its performance under hydrogen exposure.
